Fadl reported,

The Messenger of Allah ﷺ said to the people on the evening of Arafah and on the morning of Jam, when we were departing, "Maintain calm." He was holding back his she-camel until, when he entered Mina at the descent of Muhassir, he said, "You should use pebbles the size of those flicked between the fingers for stoning the Jamrah." The Messenger of Allah ﷺ gestured with his hand, demonstrating how a person flicks something with his fingers.Rawh and al-Bursani said, "the evening of Arafah and the morning of Jam," and they said, "when they were departing."
